j application mea February 1r, 1922. semina. 537,156.

To all whom t may concern.'

Bejt knownthat I, SAMUEL TRooD, a citi- Zen of the United States, residing at Haysville, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Chains, of which improvement the following is a specication.

My invention relates to 'improvements in chains, and particularly in chains used in.

connection with vehicle tires for the purpose of preventing'the said vehicles from skidding on slippery surfaces. `The several individual links of said chains are alsol applicable to and maybe used as repair links for which can be quickly assembled o'r put to- `gether Without welding or the use of rivets,-

the construction of the Wearing and connecting members serving to Without other or additional elements produce a chain of excep- 4tional strength firmly connected, and having maximum Wearing capacity Which may be formed of any vdesired length or, when formed, may be reduced in length, if required. I accomplish these objects by means of the device hereinafter more specifically described, reference beinghad to the accompanying vdrawings forming part hereof, in which: j

Figure 1 `is an elevation partly in section of the fragmentary portion of a chain showing the application of vmy improved link element. y l j Figure 2 is a side sectional elevation of a modified form of the chain. j

Figure 3 is a side sectional elevation of another modification j Fig. 4 is a view showing the application of my improved chain as a non-skid device.V

Referring to saiddrawings and particularly to Fig. 1,: t1, l 'are members made of hardened steel which constitute when assem- A of `the Wearing member.

bled the wearing surfaces of the chain which contact with the earth or ground. The said members are preferably formed of case hardened steel and are each provided with an oblong channel or orifice 2 longitudinally thereof in Which an elongated separable link 3, hereinafter called the connecting member, is inserted and seated. The said link connecting member is formed of a steel or iron rod bent to form an elongated loop, the

separable ends and the intermediate portions of which are securely held in the channel 2 of each of said link connecting members, when inserted in the'ojiening 2, project at and beyond the ends of sind opening, constituting eyes "in which the adjacent link connecting members may be secured, as shown in Fig. 1. I y,

' In Fig. 2, I show a modiliedform of my device, which comprises the` wearing members 4, each of which is provided With an orice or channel longitudinally thereof,- in all respects similar to the channel shown in Fig. l, excepting at the ends thereof a recess b is formed in Whichthe flattened separable The looped ends ends of the'link members 6 are adapted tol engage, as shown in Fig. 2. y

In Fig. 3, I show another modiiication which comprises. the Wearing members 7, each of which is provided with a channel or orifice 8 longitudinally thereof, in all re-4 spects similar to that shown in Fig. 2. The

said'channels are each provided with recesses similar to that shownA in Fig. 2, in which the separable ends of theflat link connecting members Qengage. lThe cross-sectional configuration ofthe channels or oripermit the intermediate portions of the loop connecting members tobe seated snugly Afces in the wearing members is such as Will f therein. It willbeobserved that'the Wearing members areclosely disposed and that the connecting linkl members are disposed at V right angles between the adjacent ends of j said Wearing members, and when assembled the Wearing members are so arranged with relation to each other, and with relation to the said connecting members, that the greatest dimension of the channelfin every Wearing member is alternately disposed vertically and horizontally, and the link connecting members are correspondingly disposed inv said channels, so that the-greatest transverse iop dimension of eve f link connecting member is opposed to the east transverse dimension of the channel in the Wearing members, whereby the said members are connected and securely held together `Without weld-ing and Without using any additional element or feature or construction. y

' In F ig." 4, I show my invention Aapplied to a non-'skid device or a cliainfor the pur-y pose of preventing the Wheels of vehicles skidding. In said Fig. 10, 10 are the Ausual side chains which may be made in .the usual Y manner.' 11, 1l are series of hardened members similar' in everyfres'pectto the members 1 shown in Fig. 41.., The outer ends of the *separate links of each series of saidmem- Y ing member, and. thecurved endsl projecting bers being connected tothe links l2 which are adapted to be' attached to the side chainsl Having described my invention,`what I claim and desireto secure byLetters Patent is v 1.' vA unit lfor chains comprising .a Wearing member Vhaving a -channel longitudinally thereof, substantially oblong inIA cross" sec` tional dimension, and a connecting member consisting of a rod bent to form anlelongated'l flink correspondin in configuration;v 'With said channel, the intermediate portion and the separable ends of said connecting member being seated in the channel in said Wearjfroin opposite ends of said channel.

'channels in the` wearingrinemb'ers, the interv I lmediate portions andthe separable ends of said/links being seated inv the channels Y formed in'said wearing members.

3'. A non-Welded chain comprising a A.series of wearing members, each having a channel ioaeffo' longitudinally thereof, substantially oblong jin cross sectional diniensionfand connecting members, rincluding elongated links corre-- sponding in configuration With the channels in the Wearing members, the intermediate portions and the separable ends of'said links being seated in the "channels formed in said Wearing members, the said Wearing memarranged with relation to each other when assembled, that the greatest transverse dibers'and said connecting members being so mension of every link connecting member is opposed to the least transverse dimension of the channel in the Wearing member.

4. A chain comprising a series of Wearing 4members, formed ofy hardened metal, each havinga channel longitudinally thereof subi stantially oblong in cross sectional 4dimension, and` connectingmembers, -including separable elongated links corresponding in configuration With the channels in said Wear-` l ing members, the intermediate portions and the separable ends of said links being seated vsnugly and held securely in the channels formed in said Wearing members.

5. A vnon-skid device for vehicles compris- 1 ing a series of chains formed of wearing members of hardened metal, and connecting members comprising separable links,'and a Ypair of chains to which respectively the ends ofeach of said first mentioned chains respectively are connected at intervals, each of said Wearing members having a channel lon 1- t'udinally thereof oblong'in'cross sectional il mension in which the intermediate portion and the separable ends of said connecting members are seated snugly and held securely.

In testimony whereof, I have hereunto signed inv name in the presence of two subscribing Witnesses.

In the presence of-l 'JOHN H. RONEY, CLARENCE A. WILLIAMS'.
